Rare decays at LHCb

LHCb is one of the four major experiments at the Large Hadron Collider at CERN and is custom built to look for CP violation and New Physics in rare decays of the B and D mesons. Rare decays that occur via loop diagrams provide a way to probe New Physics at energy scales much higher than can be probed by direct production. In this article, the LHCb analyses of $B \to \mu^+\mu^-, B_d \to K^{*}\mu^+\mu^-$ and $B \to V\gamma$ and their results are reported.
